Split stator manufacturing method
Disclosed is a split stator manufacturing method, which is enabled to enhance a production efficiency and to charge a thermoplastic resin between an insulator and a coil by molding the resin. The split stator manufacturing method comprises a setting step of setting an insulator and a split stator core element in a stationary mold and setting an edgewise coil in a movable mold, a resin injecting step of injecting a resin into a cavity with the stationary mold and the movable mold being half-opened, and a clamping step of clamping the stationary mold and the movable mold.
1. A split stator manufacturing method comprising the steps of:
setting an insulator and a split core element in a first mold and setting a formed coil in a second mold;
moving the second mold toward the first mold to insert the formed coil into the first mold;
injecting resin in a cavity while the first mold and the second mold are in a half-open state during the insertion of the formed coil; and
clamping the first and second molds together while keeping fluidity of the resin.
2. The split stator manufacturing method according to claim 1 , wherein the resin is thermoplastic resin.
3. The split stator manufacturing method according to claim 1 , wherein the clamping step is started in process of the injecting step.
4. The split stator manufacturing method according to claim 3 , wherein the resin is thermoplastic resin.
5. The split stator manufacturing method according to claim 1 , further comprising:
compressing the injected resin by the formed coil during the injecting step and the clamping step.
6. The split stator manufacturing method according to claim 5 , wherein the resin is thermoplastic resin.
7. The split stator manufacturing method according to claim 5 , wherein the formed coil is vibrated in a lateral direction of moving closer to or away from the insulator.
8. The split stator manufacturing method according to claim 7 , wherein the resin is thermoplastic resin.
9. The split stator manufacturing method according to claim 5 , wherein the compressing step and the clamping step are started in process of the resin injecting step.
10. The split stator manufacturing method according to claim 9 , wherein the formed coil is vibrated in a lateral direction of moving closer to or away from the insulator.
